I was pleased to have the opportunity to see the presentation Internet voting: What could go wrong? at the Information Systems Security Association (ISSA) Ottawa Chapter January 26, 2017 meeting.
Marcel Gingras has a keen grasp of the requirements for a high-integrity voting system, and provided a good history of how we ended up with the highly-ranked Canadian federal paper-based system, followed by a discussion of the risks that an Internet voting system would introduce.
